The Four-phase Killing Prison is a forbidden technique of the ancient gods.
No matter where it came from, Long Yu had never heard of such an existence. Even Yu Fei, Hong Ying and others had no idea what the ancient god's forbidden technique was.
Only the Four Phase Killing Prison that Long Yu obtained from the inheritance of the Nine Nether Dragon Emperor is an ancient forbidden technique. It is something that even the Nine Nether Dragon Emperor regards as a treasure, so you can imagine how powerful it is.
Even if he only comprehended a little bit, it would be enough for Long Yu to counterattack stronger opponents. However, he would not know to what extent he could achieve unless he tried.
Four terrifying forces gradually rose and emanated from Long Yu's body, and were felt by Shu Chan, Xi Yang Wu, Yan Huanmo and Dugu Yijian who were nearby.
A special connection was formed from the four ancient palaces under their control to Long Yu. It seemed that Long Yu was borrowing the power of the four ancient palaces!
"what happened?"
Shu Chan looked at Long Yu nervously. She had discovered that the Nine Nether Rising Dragon Formation had been destroyed by the lower and middle masters on the periphery. If she didn't think of a solution now, she and Long Yu would probably all die soon.
And now, Long Yu's abnormality seemed to indicate that he had some way to deal with the current situation. The four eerie and terrifying auras rising from Long Yu made Shu Chan shudder.
This trembling was not because Long Yu was stronger than her, but because of the nature of the four auras. Even though one of them was somewhat similar to the aura of Shura Divine Script, its eerieness was far greater than that of Shura Divine Script!
“Haha, it’s almost over. It may not be that easy to deal with the Blood Demon Princess, but if we can’t even kill a human kid like you who is a four-star emperor, then we are unworthy of being the masters of the secret realm!”
The middle-level master who had broken a small hole in the Nine Nether Dragon Formation laughed cruelly and ruthlessly. His whole body was glowing with golden light. With the power of the Golden Dragon Divine Scripture, he continued to expand the gap in the Nine Nether Dragon Formation.
The others also gathered at this gap, each condensing the power of the golden divine text and using divine formations, magical powers or divine chains. Finally, they gathered their power at one point and completely broke a big hole in the barrier of the Nine Nether Dragon Formation!
Three middle-level overlords and seven lower-level overlords finally broke through this powerful defensive barrier and came to Long Yu and others.
The fact that the Nine Nether Rising Dragon formation formed by the four ancient palaces has been able to persist until now is already remarkable. Furthermore, this is not the power of Shu Chan and the others, but only the power in the four ancient palaces.
The power of the four ancient palaces can be restored automatically. Shu Chan and others can use it, but they cannot take it for themselves. Although the power in the four ancient palaces has not been exhausted, the Nine Nether Tenglong formation has been broken by the other party, which means it has no effect at all.
"Brother Long! What should we do?"
Xi Yang Wu couldn't help but ask Long Yu a question. She had been practicing the secret martial arts method of balanced control these days and had achieved remarkable results. However, balanced control was of no use at this time.
"You go back to the Nine Netherworld first, and leave the four ancient palaces behind!"
Long Yu shouted loudly, then raised his hand and wrapped Xi Yang Wu, Shu Chan, Yan Huanmo and Dugu Yijian with the power of the world of Jiuyou Realm.
If they are willing, Long Yu can send them back to the Nine Netherworld at any time.
But he soon discovered that the four of them were unwilling to return to the Jiuyou Realm. Three of the women were very concerned about Long Yu, so of course they couldn't back down now. After all, the other party's target was Long Yu, not them.
If Long Yu was killed, there would be no point for them to hide in the Nine Netherworld.
Dugu Yijian glanced at Shu Chan, and seeing that Shu Chan did not go back, he did not go back either. The four of them stood on the ancient temple they controlled respectively, and began to actively transfer the power of the ancient temple to Long Yu.
Long Yu felt that the power from the four ancient palaces had become stronger, and he couldn't help but feel touched. At the critical moment, there were still people who would stick with him...
"If I didn't have the power of the four ancient palaces, it would be wishful thinking for me to cast the ancient forbidden technique, the Four Phases Killing Prison. However, it seems that these four ancient palaces were originally created by the Nine Nether Dragon Emperor to assist in casting the Four Phases Killing Prison!"
Long Yu guessed in his heart and was too lazy to figure out whether it was true or not. Anyway, he had obtained power from the four ancient palaces, and the four terrifying powers continued to condense in his hands!
This constantly condensing powerful force was of course also felt by the other ten powerful masters who dominated the secret realm. They were a little surprised by its terrifyingness, but did not take it too seriously. After all, Long Yu was only a four-star emperor, and compared with them, the gap in martial arts realm was really too big.
"It's almost time to end this. By the way, you are the culprit who killed the Third Prince, right? As long as we kill you, our status in the Golden Dragon Clan will be further improved, and we may even be qualified to practice the fifth-grade divine formation."
One of the middle-level masters had a golden light flashing in his hand. The eerie aura on Long Yu made him tremble a little. He couldn't help but transformed into his original form. A golden dragon monster that was more than thirty feet long roared and rushed towards Long Yu!
The golden power of the divine text condensed into countless sword lights, covering the entire space where Long Yu was, and the next moment Long Yu would be completely killed.
"Oops, not ready yet!"
Long Yu's heart was shocked. He was not yet ready to use the Four Phase Killing Prison. After all, the power of the four ancient palaces had not been fully absorbed. If he released the ancient god's forbidden technique now, he might not be able to kill all his opponents!
No matter what, now that we have started, we must do our best... Long Yu thought to himself, and directly activated the Book of Shadows, unleashing this powerful magical power!
It was at this time that Long Yu, who was originally not far from the Five-Star Emperor, finally took a step forward. Facing the crisis of life and death, the fifth innate magical fruit in his body finally underwent a transformation, and it became the Book of Shadows.
When he used the Book of Shadows, this magical power happened to break through from the Imperial Magical Power to the Emperor Magical Power, producing an extremely mysterious change. Long Yu instantly turned into nothingness and disappeared from everyone's sight.
This is true nothingness. It is not invisibility, nor is it shielding of perception. Rather, Long Yu has completely disappeared!
Everyone was shocked by this!
"Why did that boy suddenly disappear?"
The chief of the White Feather Demon Clan who was watching from the sidelines frowned slightly, feeling quite puzzled by the situation.
“Could it be that he used some kind of illusion magic? No matter what, facing the simultaneous attack of ten masters of the secret realm, even if he breaks through to the level of a five-star emperor, he will still die.”
The slightly plump Great Lord of the White Feather Demon Clan said with a chuckle.
"Yes, if the Emperor can kill ten overlords, then the whole world will probably be in chaos."
Another person also nodded and said, "No matter what tricks that kid used, he will definitely die this time. The Blood Demon Princess can't even take care of herself, let alone come to save him."
In addition to the four great overlords of the Baiyu Demon Clan who were watching from the sidelines, there were also many passers-by cultivators watching from a distance. However, they were quite far away and did not notice anything strange about Long Yu's sudden disappearance. They just thought that he had used some means of invisibility.
However, this move of Long Yu truly turned himself into nothingness!
The Book of Shadows opened a new page. After Long Yu performed this imperial magical power, his entire body completely turned into nothingness. The endless golden sword light in the sky came like a rainstorm, but it all pierced into nothingness.
"Huh? Really disappeared? Teleported to some other place?"
The middle-level master who performed the method frowned slightly, somewhat unexpectedly encountering such a situation. He immediately used a powerful detection method and sent out his divine thoughts in the surroundings, but he could not sense any breath of Long Yu at all.
He was a little confused. Long Yu clearly did not use any space magic text, so why did it suddenly disappear
But the next moment, he saw that after his golden sword rain attack ended, something like a black book page quietly appeared where Long Yu was originally, and a figure walked out of the page, it was Long Yu!
"Almost done... The first step of the Four Phases Killing Prison... Constructing the Killing Prison!"
Long Yu appeared again. At this moment, he had finally completely absorbed the power of the four ancient palaces into his body. Combined with the forbidden technique of the Four-phase Killing Prison ancient gods he had comprehended, he felt like it was about to burst out.
Endless power surged in Long Yu's body, and was finally released by Long Yu using the Four-phase Killing Prison. In an instant, lines of four colors rushed out of Long Yu's body, and in the blink of an eye, they enveloped the opponent's three middle-level masters and seven lower-level masters.
These lines were all translucent, emitting a terrifying aura that made people's hearts tremble. However, the ten masters did not take it seriously. After all, the Long Yu they were facing was too low in cultivation!
No matter how weird the moves are, there's no way to do anything to them, right
"What kind of bullshit is this? It doesn't look very powerful, but it gives me a terrifying feeling..."
A lower-level overlord frowned slightly. He was the only one among the ten people who became alert. However, it was too late to be alert now. After those lines surrounded them, they were instantly tightened the next moment, binding all ten of them tightly like a fishing net.
"Ancient God Forbidden Technique, Four Phase Killing Prison... Let me see how strong you are!"
There was a gleam of anticipation in Long Yu's eyes. The power in his body from the four ancient palaces surged out continuously, transforming into more and more eerie lines, binding up the ten powerful men who dominated the secret realm.
The Killing Prison appeared for the first time. This was the first step of the Four-Aspect Killing Prison. The first thing to do was to construct the Four-Aspect Killing Prison. Along with countless eerie lines, all ten people were tied up. A eerie murderous aura began to spread throughout the venue.
The breath of death gradually enveloped the ten people!
